I wanna get a high flow exhaust but I want to have 2 tail pipes sticking out instead of one.

Since itll most likely be a split off 1 muffler will I lose any power or will I still gain anything?

Im not trying to go fast but I dont wanna lose anything either. I just like how Big cars like Mauraders and Previous Impalas look.

nope you will be fine

Thanks pal you been real helpful with everything

What you're talking about doing is exactly what the SSE/SSEi and newer SLE'* already have.

When they mean "true" Dual exaust do they mean 2 mufflers like on a GTO?

true dual is from the headers back... 2 pipes the whole way
